A few years ago, when I was AA Gold, I got an offer for SPG Platinum for a year. It was tied into a promo where SPG would give you bonus points for each stay for the first 90 days or so, and it required setting up your SPG account to directly deposit into AA miles. Of course, I changed the setting after those 90 days, but SPG extended my Platinum status for an extra year (without me asking) after my first stay.
